Sometimes the pain we experience can be so severe that ordinary painkillers cannot control it. Do you also have such severe pain? When other painkillers have not worked or you cannot tolerate them, a doctor may prescribe you a powerful medication like this. This is a combination of two drugs called oxycodone and aspirin. Today, we will talk about this in detail, very simply.
What really happens with this medicine?
Simply put, this is a combination of two types of drugs.
1. Oxycodone: This is a powerful painkiller. In medicine, we call this an ``Opioid'' type of drug. It works by blocking pain signals to the brain. It's like closing the path that carries the pain message.
2. Aspirin: You may have heard of this one. It belongs to the category of ``NSAIDs''. That means Non-Steroidal Anti-Inflammatory Drug. Its main function is to reduce swelling and inflammation in the body.
So when these two are combined, they have a great ability to control severe pain . This medicine can be seen in the market under names like `(Endodan)`, `(Percodan)`.

Things to consider when taking medication
About pain and medication dosage
When you take this medicine for a long time, your body can become accustomed to it (tolerance). This means that you may need a slightly higher dose to control your pain than you used to. This is normal. This does not mean that you are "addicted" to the medicine. Addiction is the use of a medicine without a medical reason. Because you are in pain, you have a medical reason to take this medicine.
The most important thing is not to stop taking the medication suddenly without medical advice. Doing so can cause severe withdrawal symptoms. If you need to stop taking the medication, your doctor will gradually reduce the dose.
Drowsiness, breathing difficulties and Naloxone
This medicine may make you feel sleepy and dizzy. Therefore , avoid driving or operating machinery while taking this medicine. Drinking alcohol can make this condition worse.
If you are taking other medicines that make you sleepy (e.g. sleeping pills, tranquilizers), there is a risk of very slow breathing (CNS depression). If you have difficulty breathing, unusual tiredness, or are so sleepy that you cannot get up , it is an emergency. Go to a hospital immediately. `(Naloxone)` is an emergency treatment for `(Opioid)` overdose. Ask your doctor about this.
Stomach problems
- Constipation: This is a common side effect of this medication. If you have not had a bowel movement for 3 days, talk to your doctor.
- Stomach ulcers and bleeding: This medicine can cause stomach ulcers and bleeding. This can happen without warning . If you have stomach pain, blood in your vomit, vomit that looks like coffee grounds, or black stools, seek medical advice immediately.
Other important points
- Skin reactions: Sometimes, even weeks after starting the medication, purple or red blisters or peeling skin may occur along with fever, body aches, and rash. If this happens, see a doctor immediately.
- Pregnancy: Taking this medication during pregnancy can cause serious birth defects in the baby. Therefore, pregnant women and those hoping to become pregnant should talk to their doctor about this.
